"Tomato, broccoli, and lettuce prices have been falling for the past couple of months, as they usually do at this time of year."

Tomatoes provided the most significant price fall in November (down 45 per cent from an average price of $8.29 a kilo in October, to $4.52 in November).

Prices were also lower for chicken pieces (down 11 per cent, influenced by more discounting than in October), broccoli (down 35 per cent), strawberries (down 30 per cent), and lettuce (down 21 per cent).

Prices were higher for apples, and chocolate blocks because there was less discounting than in October. Nectarines and potatoes were also up.

In the year to November 2012, food prices dipped 0.6 per cent.

Grocery food made the main downward contribution (down 3.6 per cent).

Meat, poultry, and fish prices also decreased (down 1.7 per cent), as did non-alcoholic beverages (down 0.8 per cent).

However, fruit and vegetable prices were still up almost 8 per cent.

Fresh milk (down 9.6 per cent), butter (down 26 per cent) and cheddar cheese (down 12 per cent) all had lower prices than a year earlier.
